At first, people who are used to getting abortions will moan and cry that their rights are being violated, but then they'll realize they might have to take care of kids if they have them. Many people will have kids they don't want, and those will fill up the backlog of adoption requests for babies that currently exists today, or, they will raise kids when they are entirely unfit or unprepared at least to do so.
A generation or so will have a slightly increased rate of needs for welfare, which will create a cry for welfare "reform" (which, to liberals means "give more money" and to conservatives means "check yourself before you wreck yourself"). But, most of those kids will realize their life sucked being raised by people who shouldn't raise kids, and they will likely not have kids, or, have kids in the form of a marriage, job, etc., etc. Some of those kids will be criminals, and will increase our prison problem, which will call for more justice reform (which to liberals will mean "make less criminal things criminal, or, if you leave them criminal reduce the punishment for doing bad stuff", and to conservatives will mean, "sucks to be you if you commit a crime - we're gonna make it worse for you to try and deter future crime").
